What is a “gift”? Webster’s Dictionary defines “gift” as “something voluntarily transferred by one person to another without compensation” (I kid, I kid). In GoTaxMe: Crowdfunding and Gifts, Professor Jeffrey Kahn challenges the reader to define “gift” for federal income tax purposes in a more robust fashion than simply as transfers made with detached and disinterested generosity. Anyone who has taken a basic federal income tax class knows that § 102 excludes gifts from gross income but fails to define what gifts are. The Supreme Court filled this gap with the Duberstein “detached and disinterested generosity” standard, noting that in determining whether any particular transfer is a gift, “the most critical consideration . . . is the transferor’s ‘intention.’” Professor Kahn uses the example of the (currently) $448,162 donated by 11,709 people to former FBI agent Peter Strzok through the crowdfunding site GoFundMe.com to argue that the Duberstein standard’s focus on the transferor’s intention fails at the edges.
